This results in the use of the Just Works pairing method which does not implement any form of authentication.

Furthermore, this flaw allows attackers to interact with the device via Bluetooth Low Energy (BLE) without requiring prior authorization, potentially <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-49181-unauthorized-api-endpoint-access-leading-to-denial-of-service-and-data-leakage\/\"  data-wpil-monitor-id=\"61688\">leading to unauthorized access and data<\/a> leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-4183490\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>While the specifics of exploiting this <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-52950-unauthorized-access-exploitation-in-juniper-networks-security-director\/\"  data-wpil-monitor-id=\"79901\">vulnerability<\/a> would vary based on the attacker&#8217;s approach and the specific network environment, a conceptual example might look something like this:<\/p>\n<pre><code class=\"\" data-line=\"\"># An attacker could use a Python script to scan for vulnerable devices\nimport bluetooth\ntarget_name = &quot;COROS PACE 3&quot;\ntarget_address = None\nnearby_devices = bluetooth.discover_devices()\nfor bdaddr in nearby_devices:\nif target_name == bluetooth.lookup_name( bdaddr ):\ntarget_address = bdaddr\nbreak\nif target_address is not None:\nprint(f&quot;Found target Bluetooth device with address {target_address}&quot;)\nelse:\nprint(&quot;Could not find target Bluetooth device nearby&quot;)<\/code><\/pre>\n<p>This example simply <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-20260-buffer-overflow-vulnerability-in-clamav-s-pdf-scanning-process\/\"  data-wpil-monitor-id=\"62712\">scans for the vulnerable<\/a> device.
